Specification of Letters Patent.

Patented 0011.22, 1918.

Application filed March 13, 1918.- Serial No. 223,234.

To all whom it may concern:

.Be-it known that I, HERMAN W. TRINKLE, a citizen of the United States,residing in the city and county of San Francisco and State ofCalifornia,have invented a new anduseful Improvement in Life-Lines and LaunchingDevices Therefor, of which the following is a specification.

invention relatesto improvements in life lines and launching devicestherefor wherein a double track operates in conjunction with a line andfloats thereon to launch persons from a sinking vessel over and beyondthe side of said vessel; and the objects of my invention are First, toprovide improved means for launching persons over and beyond the side ofa ship either into the water direct or into a life boat held at adistance from the sides of the ship; T

Second, to provide means for launching a life line that willserve tohold together persons launched into the water so that said persons maycooperate mutually;

. Third, 'to-. provide improved means for controllingthelaunching of theline; and

Fourth,'-to provide a'launchin device of the character described fromwhich the line maybeeasily and readily separated in case it becomesnecessary to abandon the ship suddenly.

I accomplish these several features by means of the improved devicedisclosed 111 the drawings forming a part of the present specificationwherein like characters of reference are used to designate similar partsthroughout the said specification and drawings, and in which- Figure-1is a broken sectional view of a vessel atsea disclosing my invention in0peration;

Fig. 2-is a detailed view disclosing the manner in which launchedpassengers or per sons are held together inthe water after having beenlaunched;

. llig. 3 is an enlarged side elevation of a drum for controlling thelaunching of the line; 1

Fig. 4 is a front elevation of Fig. 3; Fig- 5: isa transverse sectionalview through the launching tracks;

' Fig.6 is a side broken elevation of Fig.5;

Fig. 7 is an enlarged detailed view of the pulley for receiving the linefrom the drum and conveying same into the tracks; and- Fig. 8 is adetailed view of the pulley at the delivery end of the tracks.

Referring to the drawings the numeral 1 is used to designate in generala ship or vessel in a sinking condition from which passengers are to belaunched, said vessel 1 being provided with the usual mast 2 and boom 3,said boom 3 being raised or lowered in the usual manner by means of aline 4 secured to the free end thereof.

On the under face or surface of the boom 3 I have secured a double track6 consisting of an inverted channel having inwardly extending flanges 7.

A. drum 8 is rotatably mounted upon the mast 2 and just below the innerend of the boom 3, said drum being provided with a suitable band brake 9andva crank 11 by means of which said drum -8 may be rotated or itsrotation retarded.

. A life line 12, having floats 14 secured thereto at regular intervalsis wound upon the drum 8 until ready for use.

Each float 14 is provided with rollers 16 on opposite sides thereof andeyelets 17 on the under side from which eyelets 17 are suspended shortlines 18 each-terminating in a snap hook '19 by means of which aperson'may be'secured to said line 18 either by fastening the line 18around: the person or securing the snap hook 18 to a life preserver orbelt.

A double flanged pulley 21 is rotatably mounted upon the underside ofthe boom 3 near the receiving end of the track 6 to engage the rollers16 on the floats 14 and deliver said rollers 14 onto the flanges 7 ofthe doubletrack or channel 6.

' A pair. of ulleys 22 are pivotally suspended from t e boom 3 and atthe delivery end of the track 6, said pulleys being. arranged to lowerthe floats 14, by means of the rollers 16 thereon, gradually from theend of said track 6.

In operation when passengers are to be launched either into a life boat25 ata distance from the vessel 1 or directly into the water, lifepreservers are assumed and. the line. 12 is paid over the pulley 21 atthe receiving end of the track 6 and the rollers 16 are launcheddirectly onto the flanges 7 of the track 6 by means of said pulley.

Passengers or persons are attached to the line 12 by securing the snaphooks 19 directly to the life preservers or by passingthe short lines 18around thepassengers and securing the hook 19*totheeyelet 17 of thefloat 14L.

- The passenger then passes over the rail and is launched into space by-means of-the short line 18 and the line 12 secured to the floatsllwithin the track 6.:

As the boom is inclined downwardly and away from the ship thefweight ofthe passenger'willmove the floats 14: andline 12 toward the delivery!end of the tracksfi. A person in charge of the life boat 25 willassistin lowering the passenger into said boat 25.

If no boat is available and the passengers are launched directly intothe water the life line 12 will serve to keep the passengers-together toobtain the benefit :ofany mutual assistance that may be available.

For instance, if several passengers who can. swim are secured to a lifeline with others passengers who cannot swim it is evident that theswimming passengers can tow the others to an adjacent shore or otherlanding without being subjected to the inconvenience or danger:causedrby the close proximityfolthose who can not swim;

After having been launched into the water, those passengers who may bepicked up by other boats may be easily released from the line 12 bymeans .of the snap hooks 19.

Having thus described my invention what I claim aslnew and desire tosecure by Letters Pateut is 1.
